Liverpool are on a 17-match unbeaten run in all competitions and host undefeated Premier League leaders Manchester City in a mouth-watering Premier League clash on Sunday.

Klopp's men were beaten 5-0 at the Etihad Stadium in September, but were only 1-0 down and causing Pep Guardiola's side plenty of problems before Sadio Mane was sent off for catching City goalkeeper Ederson with a high boot.

That incident and the subsequent result had a shaping influence on both team's seasons, according to Klopp, whose side are fourth and 18 points behind City.

"When I think about the game on Sunday, I cannot forget the first we played against them," he added. "It changed the season for City in a positive way and gave us a little knock for a few days and weeks.

"That was unlucky, it was an open game. Nobody cares about that anymore but it's the truth. We got a red card, which was the worst place in world football to be one down - wow! No chance that day."
